Is it advisable to use a database to store file modification times in PHP scripts?

Storing file modification times in a database can be useful for tracking changes and managing file versions in PHP scripts. However, it may introduce unnecessary complexity and overhead for simple applications. Consider using PHP's built-in file functions like filemtime() to retrieve and compare file modification times directly without the need for a database.

// Example of using filemtime() to get the modification time of a file
$filename = 'example.txt';
$lastModifiedTime = filemtime($filename);

echo "Last modified time of $filename: " . date('Y-m-d H:i:s', $lastModifiedTime);
